The admission control in 4G and 5G heterogeneous mobile and wireless networks will be more complex because it will need to deal with many different networks and decide to admit not only new calls and horizontal handovers, but also vertical handover calls. In this paper we propose a mobile sensitive algorithm for admission control in heterogeneous networks for seamless vertical handovers between WiMAX and WLAN. The results show that with the implementation of the proposed admission control algorithm we improve the Quality of Service of the users while moving from WiMAX into WLAN networks.
